    33This is a reasonable consequence. Before commenting I just checked sum(A) in table 10-7, and did not realise that also Table 10-8 could give useful hints.
    44So I agree that since MS say that sum of an empty expression must be zero, also sum of an empty array should be so.

     6When I wrote my comment 9 I thought of the awful things that may happen when sum() of an empty vector is used as a multiplier, if it is interpreted as zero. But since there is already a "tradition" on this (i.e. MS considers and tools and users are aware of this) my concerns are somewhat outdated.
